Description
Technical field
The utility model belongs to landscape engineering technical field, and what be specifically related to is a kind of quick salt discharge device improveing saline land.
Background technology
Saline land refers to saline Land, soil salt content is high, contained salinity has influence on the normal growth of crop, in saline land, planting plants affects by the salinity contained by soil, survival rate is relatively low, especially in landscape engineering, once geology is saline land, plant survival rate is low, and greening difficulty is very large.
The one large feature in saline land is that subterranean water level is high, and the moisture with saline land rises to earth's surface by the capillarity of soil, and form the salinization of soil of soil, the key of saline land greening is the regulation and control to soil salt.As long as the mode that the planting technique in tradition saline land is irrigated by backfilling new soil or flood is carried out, backfilling new soil need ship soil moved in improve the original in a large number from strange land, and the expense cost of buying soil and muck haulage is higher; Flood irrigates the object that can reach quick salt discharge, but need a large amount of fresh water, cost is higher, and two kinds of modes can realize afforestation effect the short time, but the duration is shorter, along with the change of environmental temperature and humidity, saline and alkaline location after improvement, the salt in the salt affected soil of bottom and alkali toward the motion of direction, ground, can destroy the root cell of plant, cause plant withered, soil alkaline problem is difficult to radical cure.
Summary of the invention
The purpose of this utility model is the above problem overcoming prior art existence, provides a kind of quick salt discharge device improveing saline land, does not use any medicament, effectively improve the salt rejection rate of soil.
For realizing above-mentioned technical purpose, reach above-mentioned technique effect, the utility model is achieved through the following technical solutions:
A kind of quick salt discharge device improveing saline land, comprise foundation ditch, described foundation ditch is divided into the saline and alkaline soil layer in top and bottom rubble filter course, described saline and alkaline soil layer and described rubble filter course are separated by non-woven fabrics, the two ends, bottom of described foundation ditch are provided with water leg, the inner side of described foundation ditch is provided with one deck antiseepage film, is provided with salt discharging pipe in described water leg.
Further, the thickness of described antiseepage film is between 1-2 ㎜.
Further, described rubble filter course comprises gravel or cobblestone.
Further, the thickness of non-woven fabrics is between 1-2 ㎜.
Optimize, described antiseepage film is HDPE antiseepage film.
The beneficial effects of the utility model are:
The utility model is novel in design, structure is simple, utilizes rainwater to carry out salt discharge to saline and alkaline soil layer, achieves original soil greening, reduce cost, saline land is laid non-woven fabrics and rubble filter course, filter underground saline-alkali water, water leg can accumulate the saline-alkali water in soil, discharged by salt discharging pipe again, limit is provided with antiseepage film, prevents outside saline-alkali water from entering base, ensure that the growth of green plants.
